Hi all!
I'm Interested in purchasing an Arduino Card because I want to build an Home Automation system. I'm supposed to build a new house in the next couple of years and I want to start designing it (even though I know I might not eventually install it in the house it's a nice thing to design and play with).
I think I'd better get the Arduino Mega coz it has more I/O connections and it seems easier than expanding a smaller Arduino with some other methods (I saw all kinds - I2C, Shift Registers and more...).
I was trying to figure out what are the differences between these Mega cards...
Can you please help understanding the differences (if there are such).

I know its a 1280 but ebay is full of these... you can barely find the 2560 at ebay.
What are the differences from the 2560 version?

the bottom two links show Arduino Mega 2560 but it looks a little different. Are there any differences?
which one should I pick?
Where can I find the cheapest 2560?
Second question -
Are all the shield fits Arduino Mega or will I be limited in shield options because I choose the Mega (instead of the Uno for example)?
Thank You all in advance!
Golan.
